This new rumored GTX 950, which might be called either 950 SE or 950 LP according to the report, would be a lower power version of the GTX 950, and would actually have a lot more in common with the outgoing GTX 750 Ti than the plain GTX 750 as we can see from this chart.

The reported specs of this new GTX 950 SE/LP would be nearly identical, though based on GM206 (Maxwell 2.0) and offering greater memory bandwidth (and slightly higher power consumption).
